Why is Your Water Pressure Relief Valve Leaking? (What to do)

The other day I noticed that my water pressure relief valve was leaking water constantly. After researching I found out that a pressure relief valve can become stuck in the open position, causing water to leak out constantly. 

I know right about now, you must be thinking if you can eliminate the pressure relief valve, but you cannot. A water pressure relief valve is a vital component of any plumbing system. 

Its main purpose is to release water from the system when the pressure gets too high, in order to prevent damage to pipes and fixtures. The very next question must be why is your water pressure relief valve is leaking?

A water pressure relief valve is usually leaking due to mineral buildup inside the valve. Generally speaking, this issue occurs in old valves or in homes with hard water. If you notice your pressure relief valve is leaking, it’s important to have it repaired as soon as possible to avoid serious damage.

A water pressure relief valve that is leaking water can be a big problem. If it is not fixed, it can lead to a loss of water pressure in your home. This can be a very dangerous situation, as it can cause your pipes to burst. 

The good news is that it is easy to troubleshoot this problem and that there are solutions.

What is a pressure relief valve? 

The pressure relief valve is an important safety feature on many types of equipment. Its purpose is to release pressure build-up in order to prevent explosions or other damage. Pressure can build up for a variety of reasons, including blocked pipes, faulty gaskets, or incorrect operating procedures. 

Pressure Relief Valve

As mentioned earlier, if the pressure relief valve is not working properly, it can lead to serious consequences. That is why it is important to make sure it is in good working order. 

Why is water pouring out of my pressure relief valve?

Water could be pouring out of your pressure relief valve for a number of reasons. Pressure relief valves are designed to open at a preset pressure and discharge fluid until pressure drops to acceptable levels. 

If you find water pouring out of your pressure relief valve, it’s likely that there is a problem with the valve itself or that the water pressure in the system is too high. 

The valve may be stuck open due to debris or mineral buildup, or it may be damaged and need to be replaced. In some cases, the water pressure in the system may be too high because there is a restriction in the line or because the temperature of the water is too high. 

If you think that the water pressure may be too high, you should check the incoming water supply and make sure that there are no restrictions in the line. You should also check the water heater to see if the temperature is set correctly. If you’re still not sure what’s causing the problem, you should call a plumber for help.

Safety Precautions

One of the most important steps in checking a pressure valve is to make sure that the electricity and gas are turned off in the unit. This is because if there is any pressure build-up in the system, it could cause an explosion or fire. 

Before checking the valve, it is important to take safety precautions by turning off the electricity and gas in the unit. To do this, locate the main power switch and flip it to the “Off” position. Then, find the shut-off valve for the gas line and turn it clockwise until it is in the “Off” position. With the power and gas turned off, you can now proceed to check the valve.

Troubleshooting A Valve That Is Leaking

Removing The Valve 

Depending on the type of valve you have, there are different ways to remove it. Consult your user manual for specific instructions. Once the valve is removed, inspect it for any damage or clogs. 

Replacing Valve

If everything looks okay, you can proceed to replace the valve. Again, consult your user manual for specific instructions on how to do this.

Double-Check

Once you have replaced the valve, double-check that both the power and gas are still turned off. Then, turn on the power switch and flip it to the “On” position. 

Next, slowly turn on the gas shut-off valve clockwise until it is in the “On” position. You should now re-establish the power and gas connection and check for leaks.

How Do I Know If The Valve Is Faulty And Needs To Be Replaced?

There are a few telltale signs that indicate that the pressure valve needs to be replaced. First, check for water leaks. If there are any leaks coming from the valve, it is likely that the seal has failed and needs to be replaced. 

Second, check the water pressure. If the water pressure is significantly lower than normal, it may be due to a faulty pressure valve. 

Finally, listen for strange noises coming from the valve. If there is a whistling or hissing sound, it indicates that air is escaping from the valve and needs to be repaired. 

If you notice any of these problems with your pressure valve, it is important to have it repaired or replaced as soon as possible to avoid further damage to your system.

Valve Is Intact, How Do I Check The Water Pressure?

Fortunately, checking the water heater pressure valve is a relatively simple task that can be easily completed at home. First, locate the valve on the side of the water heater. Next, using a wrench, screw the valve counterclockwise until it is loose. 

Finally, turn on the water supply and observe the pressure gauge. If the needle indicates that the water pressure is above 80 psi, then the valve is working properly. If the needle falls below 80 psi, then the valve may be damaged and should be replaced. 

By regularly checking the water heater pressure valve, you can help to ensure your safety and prolong the lifespan of your water heater.

What Water Temperature Is Too High?

If the reading is above 120 degrees Fahrenheit, then the water is too hot and you should turn down the thermostat on your water heater. However, if your water heater pressure valve is intact, that’s a good sign that the water temperature is not too high. 

The pressure valve is designed to release excess pressure and prevent the tank from exploding. However, if the water pressure gets too high, the valve will not be able to release all of the pressure and the water temperature will increase.

This can be dangerous because it can cause the water to become scalding hot. If you think that the water temperature might be too high, you can check it with a kitchen thermometer. Put the thermometer in a cup of water and wait for a few minutes.

Do You Persistent Leaking?

If you have persistent leaking you may want to investigate ways to reduce the mineral build up in your system. Consult a plumber about installing a water softener or look into installing a filtration system. 

Why is it important to fix my leaking water heater?

Water heaters are an essential part of any home, providing hot water for cooking, cleaning, and bathing. 

However, water heaters can also be a source of water damage if they are not properly maintained. A leaking water heater can cause significant harm to your home, so it is important to fix any leaks as soon as possible. 

Leaking Water Can:

  • Lead to Mold Growth
  • Weaken the Structure of Your Home
  • Cost You Serious Money in the Long Run

By fixing your leaking water heater, you can help protect your home from water damage and keep your family safe and healthy.

When To Call A Professional

If the pressure gets too high, the valve will release water in order to relieve the pressure. However, if the valve itself starts to leak, it can be a sign of a more serious problem.

If you notice a steady drip coming from the valve, it’s important to call a professional for help.

A technician will be able to assess the situation and determine whether the valve needs to be replaced or if there is another issue with the water heater. In either case, it’s best to leave repairs and maintenance to the experts in order to avoid making the problem worse.
